Phylogeographic lineages found in Bombus morio (183 samples) and B. pauloensis (221 samples) from 1570 bp of mitochondrial DNA (Cytocrome C oxidase I, Cytochrome B, the large ribosomal RNA subunit, and cluster 4 of tRNA, covering a region of COII and ATPase 8 genes and tRNAlys and tRNAasp). a, e coalescent bayesian phylogeny calibrated with fossils according to Hines [39] in the Thoracobombus node, that includes B. morio and B. pauloensis, dated to 13,5962 Ma (min. 7,6283 Ma, max. 21,5374 Ma). Bombus pauloensis was used as outgroup for the B. morio matrix and vice versa. Asterisks indicate clades with high support of posterior probabilities (>0.97). b, f sampling localities with the respective color found in the phylogenetic cluster. Grey areas in the map correspond to altitudes above 750 m, “X” represents missing data. c, g haplotypes networks. The size of the nodes is proportional to frequencies. Traces on the line correspond to mutational steps, and the absence of trace corresponds to one mutational step. d, h groups found in Structure software, according to microsatellite data, correlated with the clusters found in mitochondrial data. Main: main clade; TS: Teodoro Sampaio clade; C: central clade; N: north clade; S: south clade
